Bug Description

Inventory's title isn't translated as it's set in translation-mappings.json.

Steps to Reproduce

For example, set "1.13"."container.chest" to 箱子(two chinese words) in /ViaBackwards/translation-mappings.json, then start BungeeCord and server, then prepare a 1.12.2 version client and join. Open a chest, you'll find it's title is the default translation Chest, not 箱子.

Expected Behavior

Fix the translation issue.

Additional Server Info

There are some other messages not translated as I set:

Checklist

• [X] Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• [X] I have included a ViaVersion dump.
• [X] If applicable, I have included a paste (not a screenshot) of the error.
• [X] I have tried a build from https://ci.viaversion.com/ and the issue still persists.
